' The present invention relates to thread hana in the production orrayon yarn such as that manufactured according to the viscose process,

several types of thread-storage, thread-advancing devices are now beingemployed commercially. These devices are particularly useful in thecontinuous spinning process wherein the thread is caused to movelongitudinally of each or the devices in the form at a. multiplicity oihelices and during its movement is given difierent treatments thereon.Wherea the prior devices are elllcient, they are mechanicallycomplicated and ex mnsive to manufacture, install and maintain.

It is therefore an object of the present invention to provide athread-storage, thread-advanclng device that is charaterized by itssimplicity of construction and its adaptability to the use ofcommonplace materials such as glass, Lucite, etc., all of which reduceits cost of manufacture and replacement to a minimum,

A further object of this invention is the provision of a thread-storage,thread-advancing device that is self-threading and self-cleaning so thatit is particularly suitable for use in all types of rayon spinningsystems.

Another object of the invention is to provide a rotatable cage-likemember having an annular series of bars or rods for supporting a.multiplicity of helices of thread and cam means mounted on the bars orrods for applying a displacing action to move the helices longitudinallyof the bars or rods during rotation of the cage-like member,

Other objects and advantages of the invention will become apparent fromthe following detailed description when considered in connection withthe accompanying drawings wherein:

In the drawings and more particularly in Figurea 1-5, inclusive, thenumeral it indicates a drive shaft-which is mounted in hearings, notshown. Drlveshaft It is reduced at it to receive hub ll of circularplate 13. Huh i2 is keyed to reduced shaft portion H and the platetherefore rotates with the shaft. Plate l3 forms a cover for a cupmember l4 and with the cup member constitutes a. housing generallyindicated at 15.

Clup member H is provided at its center with an opening to through whichshaft it extends. Series of annularly arranged openings l! and i8 arformed in plate l3 and cup member l4, respectively. Parallel bars 19 arearranged in annular formation and each bar extends through one of theopenings H in the plate and into'the corresponding opening it in thecup. The bars are anchored within the openings ii in the cup member bymeans of lock screws 20. Plate l3 and cup member H are secured togetherby means of bolts 2!. Housing i5 is secured in fixed position forrotation with shaft in bymeans of a cap nut result in rotation ofhousing l5 an the bodily rotation of bars 19 and that the housing andbar form a rotating cage-like structure.

A tubular shaft 23 is mounted for rotation upon shaft Ii. Opening IS incup member i4 is sufilclently large to permit tubular shaft 23 to extendwithin housing ll although the walls of the opening closely encircle theshaft. Shaft 23 is provlded with an annular flange 24 at its inner endand a sun gear 25 keyed to tubular shaft 23 abuts against the flange.Planet gears 26 are positioned within housing 15, each of the planetgears being rotatably mounted upon one of the bars IS. The planet gears26 are each formed with an' annular flange 2! extending in the directionof plat I3, the flanges being spaced from the bars l9 sufficiently toprovide a recess for the mechtion of the inner ends of coil cam members28. Each bar I9 has one of the coil cam members 28 rotatably mountedthereon and each coil cam member is secured within the recess of itsrespective planet gear for the purpose of causing the independentrotation of the coil cam member about its supportin bar. The outer endsof the coil cam members terminate in a plane with the ends of theannularly arranged bars IS.

A bevel gear 29 is keyed to tubular shaft 23 at the end remote fromflange 24. Gear 28 is maintained in position upon the shaft by means ofa nut 30. Suitable means, not shown, are utilized for driving shaft 23and sun gear 25 through the medium of gear 28 and suitable means,similarly not shown, are provided for driving shaft IO.

In the manufacture of Viscose rayon the Spin- 4 thereon. Since thedriving of shaft 23 at onehair the speed of shaft l effects relativerotation between sun gea'r and planet gears 26, corresponding relativerotation will be had between coil cam members 28 and the respective barsll. Therefore a the yarn i wrapped about the outer surfaces of the barsI8 and the cam members are rotated with respect to the bars,

the thread lying between the cam surfaces will 1 yarncontacting surfaceportions of the bars may ning solution is extruded through spinnerettesinto an acid treating bath whereupon the resultant yarn is subjected tovarious treatments, depending upon the particular type of yarn beingproduced. It is customary to stretch the yarn as it isdrawn from theacid bath and to subject it to a series of treatments, that is, washing,desulphurizing, further washing, bleaching, still further washing anddrying. A series ofdevices of the form illustrated in Figures 1-5,inclusive, are admirably suited for handling yarn during the continuousproduction of rayon wherein the yarn is subjected to several treatmentsprior to collection, as it is advanced linearly in helical form. Inutilizing the device as thus described in the manufacture of rayon, aspinning solution is extruded into an acid bath. Shafts II and 23,having been set in motion with resultant rotation of the cage-likestructure formed of the housing [5, the extending bars l8 and coil cammembers 28, the leading end of the thus formed yarn A is placed upon thebars, l8 adjacent plate I3. convolu ions of the yarn A will then formupon the bars and the continuance of the operation will result in theautomatic threading of the yarn until a helix is formed extendingthroughout the length of the bars. The leading end of the yarn will thenpass from the cagelike structure and move downwardly where it may bethreaded in the manner described upon a similar device. This proceduremay be continued in the threading of several thread-storage.thread-advancing devices until the yarn reaches the point of collection.I

In the form of device illustrated in Figure 1 inclusive, there is a 1:2ratio between the planet gears 26 and the sun gear 25. Since the yarn isdelivered to the cage-like structure at a linear speed equivalent to thespeed of bodily rotation of the outer surfaces of bars l8, it isnecessary that the speed of rotation of shaft 23 be one-half that ofshaft l0 when it is desired that consecutive convolutions of yarn bespaced one cam apart within the coils of the cam member 28. However, theconvolutions of the yarn may be spaced more than the distance betweenthe coils of members 28 by varying the relative speeds of shaft I0 andshaft 23. Wider spacing of the convolution may be obtained by drivingshaft 23 in a counter direction to that of shaft I8.

I In referring specifically to the operation of the relative parts ofthe device it will be seen that the driving of shaft l0 causes bodilyrotation of bars l9 and the coil cam members 28 be provided with one ormore longitudinal corrugations. Continued rotation of the cage-likestructure will form a helix of the yarn. As

be treated with liquids either by spraying of the same upon the yarn orby immersion of the device with the yarn thereon within a liquid bath.

In a modified form of the invention illustrated in Figures 6-9,inclusive, shaft 3| is mounted in bearings, not shown, for supportingthe device.

Plate 32 is secured to the free end of shaft 3| between a flan e 33 onshaft 3| and a washer 34 held in position by a bolt 35 threaded into theend of the shaft. Plate 32 constitutes a cover for cup member 38 andtogether they constitute a housing generally indicated at 31. .A seriesof annularly arranged bars 38 extend through openings 39 arrangedadjacent the periphery of plate 32 and the inner ends of the bars areanchored in corresponding openings 40 in cup member 36 by mean of lockscrews M. Since the plate adjacent the central opening thereof isclamped between flange 33 and washer 34 the rotation of shaft 3! willresult in the rotation of housing 31, together with the bodily rotationof bars 38. A coil cam member 42 is mounted for rotation upon each ofthe bars 38, the ends of the coil cam members extending through openings39 in plate 32 and terminating adjacent the inner wall of cup member 36.A tubular shaft 43 is mounted for rotation relative to shaft 3| and theinner end of the tubular shaft extends through the closely fittingopening 44 at the center of cup member 35. A sun gear 48 is keyed to theinner end of shaft 43, the sun gear 45 being in mesh with two series ofplanet gears 46 and 41, respectively. Each planet gear of the respectivesets is mounted upon and fixed to the inner ends of one of the coil cammembers. The planet gears of the set adjacent plate 32 have hubsextending in the direction of the inner wall of cup member 36 whereasthe other set of planet gears have their hubs extending in the directionof plate 32.

The planet gears of the respective sets are alternated upon the bars 38.The planet gears are approximately one-half the width of the sun gear.Since the gears are preferably of such size that there is a 1:1 ratiobetween the planet gears and the sun gear, the planet gears of therespective sets will overlap in the manner illustrated in Figure 9. Byproviding two sets of planet gears it is possible to construct a verysimple and efflcient device in which the sun gear is held stationary andthe ratio of the planet gears to the sun gear is 1:1 and in which eightannularly arranged bars 38 with their respective coil cam members may beutilized.

In the modified form of device illustrated in Figures 6-9, inclusive, alatch member 48, secured to a fixed part of the mechanism in a mannernot shown, has its end insertedin depression 49 of shaft Plate 32 andcup member are secured together in operative position by means ofcountersunk screws '50 threaded into openings 5! in plate/32.

Operation of the device illustrated in Figures 6-9, inclusive, issimilar to the operation of the form heretofore discussed. In operatingthis form of the present invention, rayon yarn is drawn from thecoagulating bath and the leading end thereof placed upon bars 38adjacent plate 32. The cage-like member formed of the bars, the housingand thecoil cam members, having previously beenset in motion by therotation of shaft (ii, the yarn begins to wrap about the cage. Duringthe entire operation sungear 45 is maintained stationary with itstubularshaft N by means of latch member at. As the ratio of each of theplanet gears to the sun gear is 1:1 and as the yarn ls""tal en up by thecage-like member at a speed equivalent to'the movement of the outersurfaces of bars 33, the relatively moving coil cam members will causethe turns of yarn to be spaced along the bars with the yarn of the turnslyingbetween adjacent cam surfaces in the respective coil cam members.The continued operationof the device will cause the yarn to travel in ahelical path with the production of a yarn helix extending throughoutthe length of the bars 33. As stated, the turns of yarn will be spacedone coil apart in each of the coil cam members. Further operation of thedevice will, with continued delivery of yarn to the surfaces ofthe barsadjacent plate 32, result in the maintenance of thereferred to helixwith the continued discharge of yarn from the ends of the bars. The yarnin the helix is therefore progressively moved in an axial directiontoward the point of discharge. The device illustrated in Figures 6-9,inclusive, like the device illustrated in Figures 1-5, inclusive, maybeutillaed in series with similar devices and the yarn may be subjectedto various treatments on each of the devices in its passage to a pointof collection.

In the continuous manufacture of viscose rayon as well as in thetreatment of other thread, the process involves a plurality of liquidtreatments of the yarn or thread as it is conducted linearly. In Figures10 and 11 of the drawings a modified form of the device constructed inaccordance with this invention is illustrated, the device beingprimarily intended for the passage of yarn helically while it issubjected to several liquid treatments on the same device. Since it isnecessary to separately recover and recircuiate'at least some of thetreating liquids after reconditioning of the same in order for theviscose rayon process to be commercially feasible this form of deviceis. constructed in' a manner to cause the yarn to assume a plurality ofseparate support of the device. The drive shaft is secured in bearings.not shown. Shaft 52, is reduced at I! to receive thereover a plate 54which is keyed to the shaft as at 55. A cap nut '56 is provided forsecuring the plate in position upon the shaft.

' cover for a cup member il, plate 51 and cup member 8! forming ahousing designated gen-- orally at 82. Cup member M is provided at itscenter-with an opening 63 through which shaft 52 extends. A series ofannularly arranged openings El and 65 alefomied in plate 57 and cupmember 6i, respectively. Parallel bars 66 are arranged in annularformation and each bar exof the bars are received in said openings.

and into housing 62.

tends through one of the openings M in the plate and into thecorresponding opening 55 in the cup. The bars are anchored within theopenings 85 in the cup member by means of lock screws Bl. Plate and cupmember at are secured together by means of bolts lid.

It will be seen that housing 52 is fixed for retation with shaft 52 bythe key 59. The ends of bars 56 are reduced at (is and plate 51 iprovided with a number of openings corresponding to the numherof barsto. Reduced portions till As shown in Figure 11 the openings in plate 54are each formed in an car it, a series of which ears corresponding tothe. number of bars 6t; extend around the periphery of plate 56. Tubularshaft II is mounted for rotation upon shaft 52. Opening it in cup memberti is sufficiently large to permit tubular shaft Hi to extendtherethrough The walls of opening Eli closely encircle shaft 'll.

Shaft H is provided at its inner end with an annular flange l2 and a sungear i3 is keyed to shaft ll as at it. Sun gear I3 abuts against flange12 of the shaft. Planet gears 15 are Dositioned Within the housing 52and each of the planet gears is rotably mounted upon one of the bars 86.Planet gears 15 are each formed with an annular flange 15 extending inthe direction of plate 51. Flanges '58 are spaced sumciently from bars66 so that recesses are provided adjacent the bars for the reception ofthe inner ends of coil cam members indicated generally at ll. The coilcam members are provided with a plurality of series of closely spacedconvolutions the series being designated as 13,19, and 80, respectively.For the purpose of transmitting a rotary motion to the separate seriesof convolutions in each coil cam member I1, wide angled convolutions GIand 82, respectively, are utilized to connect the adjacent series.

A bevel gear 83 is keyed to tubular shaft II at the end remote fromflange [2. Gear 83 is maintained in position upon the shaft by means ofa nut 84. Means, not shown, are utilized for driving shaft H and shaft52 to effect rotation or housing G2 with shaft 52 and rotation of sungear 13 with shaft H, The 'shafts are driven 'at different speeds toeffect relative motion between the sun gear and planet gears withcorresponding rotary motion between coil cam member-s11 and the bars 86upon which they are respectively mounted.

In the manufacture of viscose rayon involving the use of the modifiedform of device shown in Figures 10 and 11' the yarn is drawn from thespin bath in the same manner described in connection with the operationof the device of Figures 1-5, inclusive. Upon rotation of shaft 52 andthe rotation of haft II at arotary speed one- 7 half that of shaft 52ahelix of yarn will form on bars 98 with the turns thereof lying betweena'djacent convolutions of the closely spaced coils in series 18. Uponcontinued operation the yarn will be caused to progress along the barsin helical form until it reaches plate 54. Due to the formation of thewide angles in the convolutions of the coil cam members at 8| and 82,widely spaced turns will occur in the yarn helix at these points. Thewidely spaced turns will constitute a separation zone for the closelywound yarn grouped in the several series of helices.

' It is possible due to the separation of the series of closely spacedhelices of yarn to apply a separate treating liquid to each of the yarnhelices and to separately collect the liquids in trays arranged belowthe device, at least without a prohibitive amount of mixing of theliquids.

The yarn may be readily discharged from the end of the device, as itspassage is not retarded by cars 18 on plate 54, whereupon if desired theyarn may be then conducted immediately to a collecting device or theyarn may be subjected to drying and thereafter collected.

Inthe continuous manufacture of viscose rayon it is desirable to dry theyarn before it is collected. When viscose rayon yarn is dried it shrinkslinearly and therefore a method of continuously drying yarn in linearform upon supports must provide means on which the yarn may theretoplate 89 secured in position by cap nut 81. Plate 86 is dished in such amanner as to 'provide it with an angularly disposed rim 88.

Plate 86 forms a cover for a cup member 89 likewise provided with anangularly disposed marginal portion 90 which extends parallel to rim 88of the plate. Cup member 89 and plate 86 constitute a housing 9|. Atubular shaft 92 is carried by shaft 85 and a sun gear 93 is mounted onthe inner end of the tubular shaft. Shaft 85 and tubular shaft 92 extendthrough a closely fitting opening at the center of cup member 89. Abevel gear 94 is secured to tubular shaft 92 for the purpose of drivingthe same from a source of power, not shown. A series of converging bars95 extend through openings 96 in rim 88 of plate 86 and the inner endsof bars 95 are anchored within openings 9'! in cup member 99. Lockscrews 98 are provided for securing the ends of bars 95 within theopenings in the cup member.

Planet gears 99 are mounted on bars 95, the planet gears 99 and the sungear being beveled suillciently to accommodate the angular dispositionof the planet gears and the sun gear as a ures 12 and 13 the yarn isdelivered to the bars adjacent plate 86 following the liquid treatmentthereof and upon rotation of shaft 85 and tubular shaft 92 a helix ofyarn will be formed upon the bars, the convolutions of yarn beingadvanced in the manner heretofore described in connection with the otherforms of the invention. Upon rotation of shaft 92 at a speed one-halfthat of shaft 85 the'turns of yarn will be maintained between adjacentcoils of the coil cam members throughout the length of the helix. Theyarn in its travel upon this modified form of devices will be deliveredto the bars adjacent plate 86 in wet condition and the yarn will move ina helical path.

result of the angular mounting of bars 95. Planet The helical path issuch that the turns or convolutions thereof are constantlyhecreasing indiameter and substantially dry yarn will be discharged from the free endof the device. As the yarn is passed over the device and dried by anysuitable means, not shown, it will shrink and therefore the yarn willclosely adhere to the outer surfaces of the bars and will therefore beconstantly displaced toward the discharge end of the device. It is to beunderstood that in utilizing a drying device embodying the principleshere involved, similar results may be obtained by substituting conicalbars and conical coil cam members for the converging bars andcoil cammembers.

While the central shaft has been illustrated in each of the figures asthe means for propelling the cage-like member formed of the bars, coilcam members and the housing, and the sun gear has either been maintainedstationary, as shown in Figures 6-9, inclusive, or driven by the tubularshaft, as shown in the remaining figures, it is to be understood thatthe tubular shaft may be utilized to drive the cage-like member and thecentral shaft maybe utilized to drive the sun gear or to hold it instationaryposition, as desired.

It is likewise to be understood that various means may be utilized fordriving the cagelike member and effecting the relative movement of thecoil cam members about their respective bars without departing from thebroad aspects of the invention, and thatthe distance between theconvolutions of yarn may be modified as desired by driving the coil cammembers at an appropriate speed, depending upon the speed of rotation ofthe cage-like member.
